* Level-Appropriate Quests: Don't stay questing in zones if you out level them. As soon as you reach the appropriate level to quest in a higher zone, be sure to do so to take advantage of the higher experience gain. The exception to this is if the end of a quest line provides fast transport to a new zone, but this would require intimate knowledge of zones and quest lines.
Common methods of power leveling include doing only those quests which are most efficient in terms of experience over time, and analyzing the quests in a given zone so as to do them in the most efficient order possible. Remember, the idea of power leveling is speed and efficiency--you may wish to obtain an addon that will show you how much experience per hour you are gaining to test your techniques. Additionally, ensure your character's talent build is crafted for maximum endurance. You want as little downtime (walking, drinking, eating, crafting, typing, etc.) as possible.
Let's face it, World of Warcraft has an awful lot of content available, especially when it comes to end game content. Unfortunately, that can quite time consuming and not everyone can afford to spend so much time getting there. Wouldn't it be great if there was a way to skip all the grueling and time-consuming leveling process and just jump right into the end game? Thankfully, there is - WoW leveling service!
